Cameron Douglas, doing hard time for his years of drug use and distribution, was attacked in prison and had his leg and a finger broken, The New York Post is reporting.

Cameron, 34, became the target of a New York mobster who put a mere $100 bounty on Michael’s famous son, a source told The Post. It was payback for the fact that Cameron had ratted out his drug suppliers during his original sentencing hearing, information that was inadvertently revealed during a 2010 bail hearing.

As RadarOnline.com previously reported, Cameron’s testimony against the dealers helped get him a five year, instead of 10 year, sentence in 2009. But he later earned himself an additional four and a half years behind bars for smuggling in heroin and a prescription narcotic while at the Metropolitan Correctional Center.
